w vs w, last round of a Swiss teams, playing for the second place (nothing of this really matters...), you hold: ♠ATxx ♥xx ♦AJxxxx ♣x Bidding goes: 2♦* Pass 2♠* 3♦ Pass ??? 2♦ is multi (weak in a Major, strong in NT) and 2♠ means P/C with preference to hearts. 3♦ by partner is natural. What do you bid?
